IMPROVEMENT IN MOWlNG-MAC-HINES.

Specification forming part of Letters Patent No. 28,628, dated June 5, 186i).

To all whom t may concern:

Be it known that I, CHESTER BULLooK, of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and usefullmprovements on Blowing-Machines; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the letters and marks thereon.

Of the drawings forming part of this specification, Figure l is a bottom or under side view ofa mowing-machine having my improvements, the finger-bar and cutter-bar attached thereto being held up by the side of the body or frame of the mower. Fig. 2 is a top view, or a view of the upper side, of such machine, with the finger-bar and cutter-bar extended out, in its operative position, a portion of the finger-bar shown removed. Fig. 3 is a top view of a portion of the finger-bar and cutterbar and of the means attached to them, showing` the manner of' attaching the base of the cutters to the cutter-bar, the top or clamping piece for keeping cutters and cutter-bar in place being represented separate and detached by Fig. 4. Fig. 5 is a longitudinal sectional view ofthe inner portion of the cutter-bar, showing the swivel-joint Limiting it to the connecting-rod; and Fig. 6 is a sectional view of the same parts, as shown when the bars are held up by the side of the mower-frame, as represented by Fig. 1. Y

In each of these figures the same parts .are indicated by the same marks and letters.l

As parts of this mowing-machine are or' common use,I will only describe such as are of my invention, or so connected with those parts as that description of or reference to them is necessary.

rI he first part of my invention relates to an arrangement of means for connecting the frame or bars of the fingers and cutters to the frame or body ofthe mower.

The second part of my invention relates to an arrangement of means for suspending the frame or bars of the fingers and cutters bythe side of the mower frame or body.

The third part of my' invention relates to means for uniting the cutter-bar to the connecting-rod.

The fourth part of my invention rarelates to the means for connecting the draft-pole with the frame of the machine and with the frames that are attached to the cutter and linger bars.

The fifth part of my invention relates to the manner of attaching the cutters to the ngers and to the cutter-bar.

The first part of my invention is thus carried out: I place'behind the axle or main shaft to of the machine a shaft, b, supported by suitable beariugs, c, which are affixed to the bars d of the machine. Thisshaft b derives its motion from shaft'Athrou gh the medium of geared 0r toothed wheel c upon shaft a, and pinionj', attached to a collar, g, around shaft b, pinion fbeing in communication or gear with wheel e or not, as pins h on the end of shaft b are in Vrecesses i in the side of pinion f or not, the means for putting in or out of' gear the wheel and the pinion being a lever, j, the forked end of which embraces the collar g at k, its fulcrum being atl, and its front end, m, having a piu to fit into a hole in one of the bars of the frame. At right angles to shafts a and b, I place a third shaft, n, in bearings o of a hinged or vibrating frame, one of the side bars, p, of which embraces shaft b, and the other side bar, q, being hinged to aplate, r, with apart ofa hinge to side bar, s, of the frame of the mower. A portion of this frame of the third shaft, n, is half-tubular, t, and covers one side of the shaft, while other portions are strengthening-bar u, a bearing-barn), andaconnecting-bar, ic. The front end of shaft n passes through a bearing on bar and has at this end a disk, y, secured to it, having a crank-pin, z, to which one end of the connecting-rod c is attached. rlhe inner end of shaft n has a beveled pinion, y', which gears into the beveled wheel fr on the shaft b, and through this gearing shaft n derives its motion. Bar 00 is connected to bar w, and extends in a line at right angles to the shaft n out to the embracing shoe-bar w on the finger-bar o. A pin, u', passing through the outer end of bar m, shoe-bar w', and linger-bar c', attaches these bars at this point and forms a pivot upon which the finger-bar turns. The

cutter-bar is connected to shaft n by the rod z', the outer end of' which is bent and turned into the swivel t', the point or pin of thel swivel passing through the cutter-bar, and thus, in

conjunction with the pin u', completing the coni l nection between the frame or bars ot' the cutters and fingers and the frame or body of the mower. By this arrangement of means the fmger-bar, with the cutter-bar, is susceptible of being raised orlowered as a whole, or the outer end ot' the finger-bar being raised, while the bars will continue in tle. same relative position to the connecting at all positions, and the cutters can be kept iu motion also at all positions or inclinations.

1n cari-5 ing out the second part of my invention facility is aftbrded by the attachment otl the frame ofthe third shaft, n, to the shaftb and to the bar s, and by the movement ofthe bar fr upon the end of' the shaft n; but the means more particularly involved under this part of the invention are' the following: thejoint attat-hing the bar a' to the iinger-bar, that which attaches the connecting-rod to the cutter-bar, the clamping-band s at the inner end of bar which, when the extended part q of the tingerbar c' is underneath the bar w,tits upon the notched end r and keeps this end of the iinger-bar steady, the rollerp on a small shaft, o', afixedto the box of the draft-pole, and the bracket n at the, rear part of the mower-frame. It will readily be seen how by these means the nger-har and cutter-bar are permitted to be moved from their operative position to that position where they are safely kept by the side ofthe mower when it is transported or moved from one locality to another. The use ot' ally f the roller p', and supports the front end of the cutter and iinger bars by passing through a ring,j, attached to a stud, t, of the bar w.

The means used for uniting the cutter-bar to the connecting-rod, which constitute the third part ot' my invention, are more specially shown in Figs. 5 and 6. From an examination ofthese tigures it will be perceived that the innerendot'thecutter-baristhickened,and that through this thickened part a horizontal slit, h', is made, and also a vertical slit, g', while a hole is also made throught that part which lies below the horizontal slit. A swivel of a peculiar form is fitted to the cutter-bar by means ofthe hole and the slits, andis made the means,

in connection with them,i`or attaching the connecting rod and the cutter-bar, and of allow-- and the body immediately below the eye in the vertical slit. When the bar is in position for use the lips ot' the swivel lie under the lips of the bar, as shown bv.Fig.5, and aid in strenghtening this end ofthe bar; but when the bars are held up by the sido of the mower-frame they lie in line with the slit and allow of easy motion of this end of the bar.

The draft-pole b', named as within the fourth part or my invention, is not rigidly coo` nected to the frame of the mower or the machine, but is only titred into boxes k lc", within which it has longitudinal movement. A stud or projection on its under side at a limits its backward orinward movement, and a spring-catch, a, resting against an eyeJ/f, assists the stud, while it also aids in the forward motion ot' the pole. When the cutter-bar is in use the chain m is not passed over the roller p', but after passingthrough theeyej goes direct tothe lever l,'the upperend ot'which lever is within reach of the drivers hand, and may be. used by him to raise or lowertheframe of the tnger and cutter bars. Through this arrangement of the chain and pole the side drait of the cutter and finger bars and frame is entirely relieved. When the cutter and tinger bars and i'rame are held up by the side ofthe mower or machine frame the chain m is passed around the roller p', and thus the weight transferred from the end of the pole to the side of the machine-frame.

The manner of attaching the cutters to the fingers and to the cutter-bar, which forms the i'th part of my invention, is shown by Figs. 2, 3, and 4. The points of the cutters e are placed in recesses in the base ofthe ngercapsf, and have some play therein. At their rear ends the cutters have a pin, g, which ts into a hole in the cutter-harm. The finger-bar c is recessed for the cutter-bar, and also for a clamping-bar, h, and, as shown by Fig. 4, the clamping-bar has arms i with slits j", and by screws Z4', passing through these slits into holes in the finger-bar at mt, the clamping-baris secured to the finger-bar, overlying the cutterbar and allowing it free motion underneath. The drawings show the clamping-bar extending over the base of three cutters only; but, as is evident, it may extend over the entire numberl of cutters to the extreme ends of the fingers; or it may pass over only a few cutters, there being several clamping-bars over the series ot'cutters and between the inner and outer ends of the inger-bar. This manner of securing the cutters to the fingers and to the cutterbar allows them to have a drawing cut upon the grass or grain, as the point of the cutter by the movement of' the cutter-bar will have an in-and-outmotion'in therecess of' the finger.

While this machine can be used for any and all purposes for which mowers are generally used, the arrangement and construction of certain parts of it will allow its use with great efficiency as a hedge trimmer. The tongue and cutter-bar, it will be perceived, having an unusual range within which they can be moved, gives to this machine the facility and ease ot' the frame ot' the cutters and fingers by the side ot' the mower.

3. The means recited for uniting the cutter bar to the connecting-rod.

4. The arrangement of means described for connecting the draft-pole to the mower or machine frame, and for the purposes set forth.

5. The manner ot attaching.;` the cutters to the Ingers and cutterbar described.
